Company profile

researched Aug 2026

Sorting Robotics is a Los Angeles-based cannabis manufacturing automation company that designs, builds, and deploys robotic systems for pre-roll production. Its product fleet includes WavePak, a cone filling machine using harmonic wave technology rated at 4,000 pre-rolls per hour; Jiko+, a pre-roll and hash-hole infusion system engineered for high-viscosity rosin and hash concentrates at 1,200 units per hour; Stardust, a kief coating robot rated at 1,600 coated joints per hour that also works with bubble hash, distillate, or other binders; and Telti, autonomous teachable robot arms for packaging and general production-line tasks, listed as coming soon. Sacra additionally describes an Omnifiller vape cartridge filling system and MoonGlue, a plant-based rolling adhesive sold as a standalone consumable.

All machines integrate with LAKA, the company's production analytics platform, which tracks cycle counts, quality metrics, and maintenance needs in real time. Operators load pre-rolls into fixtures, select infusion recipes on touchscreen interfaces, and monitor production through integrated cameras and sensors; Stardust uses a Kawasaki 6-axis robotic arm with computer vision. The company states typical dose accuracy of ±0.05g and a typical payback period of under 12 months, with 250+ active deployments worldwide.

Alongside catalog machines, Sorting Robotics operates a custom integrations practice with a five-phase engagement model spanning discovery call, on-site facility walk, design spec with throughput modeling and line-integration drawings, fabrication in Los Angeles, and on-site installation, commissioning, and operator training.

Founding story

The founders spent the 2010s at NASA and JPL building landers, rovers, and precision manipulators, including major components for the Mars Rover, systems required to run for years without servicing. The company was founded in 2018 by three engineers working on a card sorting machine and joined Y Combinator's Winter 2019 batch. Examining cannabis manufacturing in 2020, the team identified the same throughput-versus-consistency problem it had addressed in aerospace and pivoted the business to build industrial tooling for the category.

Business model

Sorting Robotics sells manufacturing equipment directly to licensed cannabis producers under a B2B hardware-plus-software model, with machines priced from roughly $90,000 (Jiko) to $250,000 (Stardust). Beyond catalog machines, it acts as a systems integrator via its Custom Integrations and Automation Service, designing and deploying complete production lines, which lets it address larger portions of customer capital expenditure budgets while embedding its LAKA analytics software as the production orchestration layer. Sacra reports gross margins above 50% and states the company has been profitable since 2021.

Revenue comes primarily from upfront equipment sales, complemented by recurring income from consumables such as MoonGlue adhesive, maintenance, and software subscriptions, plus custom integration and systems-integration projects that can be one-off or multi-year builds. Because cannabis regulation prohibits interstate commerce and requires in-state production facilities, multi-state operators create repeat purchasing opportunities as they expand.

Traction

Sacra estimates $7 million in 2024 revenue with management forecasting $11 million for 2025, gross margins above 50%, and profitability since 2021. The company reports five shipped products, 250+ active machine deployments worldwide, and deployments across more than 120 facilities in the U.S. and Canada (the company's integration page cites 150+ facilities). Approximately 30 Stardust units have been sold along with hundreds of lower-priced machines since the first cannabis robot shipped in 2021. Headcount is listed as 15 on the company site and 12 on its Y Combinator profile.

Latest developments

Telti, an autonomous teachable robot arm for packaging and unstructured assembly tasks, debuted at MJBizCon in 2025 and is listed as coming soon on the company website. WavePak, a pre-roll packing machine rated at 4,000 units per hour, was publicly shown in 2026. The company reports five shipped products, 250+ active deployments, and 15 employees across engineering, operations, and go-to-market, and is hiring robotics software and mechatronics engineers in Los Angeles.

Full profile — market position, technology, go-to-market, geography, history, risks & controversies

Market position

Sorting Robotics focuses on specialized, higher-priced infusion and coating equipment within cannabis pre-roll manufacturing, a niche where it says few competing catalog machines exist. It competes with vertically integrated pre-roll line providers such as STM Canna (whose RocketBox Pro is priced at $59,900 and processes 5,000 pre-rolls per hour) and Canapa by Paxiom; with Accelerant Manufacturing's production-as-a-service model that converts equipment capex into a per-joint fee; with rolling and cone-filling specialists RollPros (Blackbird/TruRoll) and GreenBroz (Holy Roller); and potentially with traditional tobacco equipment manufacturers such as Körber, which has expanded into hemp production. Reported customers include Stiiizy, Tilray, and Blue Fox Brands.

The company positions its engineering pedigree — founders and engineers who worked at NASA and JPL on landers, rovers, and precision manipulators — as the basis for reliability in a category it describes as lacking industrial-grade tooling. It states that generic pick-and-place automation designed for pharma or food jams, smears, or degrades terpenes when applied to flower, kief, and live rosin, and that there are few reliable catalog machines for hash-hole, solventless infusion, or kief-coated cones at scale. Stardust is described as the first machine to automate kief coating. Every machine is manufactured, tuned, and QA'd within 20 miles of the company's Los Angeles shop, and the Jiko infusion system is described as patented.

Technology

Precision robotics combined with computer vision and AI. Stardust uses a Kawasaki 6-axis robotic arm with computer vision to apply kief, bubble hash, distillate, or other binders to pre-rolls with recipe-controlled dusting. Jiko injects concentrate through a heated, pressure-regulated system with advanced heat control for high-viscosity rosin and hash. WavePak uses harmonic wave technology with self-adjusting density for cone filling. Telti provides autonomous decision-making for unstructured assembly. LAKA, the company's production analytics platform, integrates across machines to track cycle counts, quality metrics, and maintenance needs in real time, with cameras, sensors, and touchscreen recipe selection at the machine level.

Go-to-market

Direct sales to licensed cannabis producers, brands, growers, and co-packers, supported by live product demos and ROI assessments booked through the company website, a free engineering assessment offer for custom integration prospects, an in-house sales team of account executives led by a chief revenue officer, and trade-show presence including MJBizCon, where Telti was unveiled. Customer testimonials and trade-press coverage in outlets such as Cannabis Tech and Cannabis Science & Technology support the funnel.

Licensed cannabis manufacturers, brands, growers, processors, and co-packers, including multi-state operators and high-volume producers making more than 100,000 pre-rolls per day. Named customers and reference operators include Stiiizy, Tilray, Blue Fox Brands, Delta Munchies, HoneyKing, and Pecos Valley Production.

Geography

Headquartered and manufacturing in Los Angeles, California, with all machines built within 20 miles of its shop. Systems are deployed across more than 120 facilities in the United States and Canada, with the company citing 250+ active deployments worldwide. Technicians travel to customer sites for installation, commissioning, and operator training.

History

The company was founded in 2018 in Los Angeles by three engineers working on a card sorting machine and was accepted into Y Combinator's Winter 2019 batch. In 2020 the team redirected its robotics work toward cannabis manufacturing and built the first Jiko, which reached customer floors in 2021 at about 1,000 infused joints per hour. Stardust, an automated kief coating robot, launched in 2023 after a four-month development cycle. Telti, an autonomous robot arm for unstructured assembly, was unveiled at MJBizCon in 2025, and WavePak, a precision pre-roll packing machine, was shown publicly in 2026. As of the company's about page, it has shipped five products and deployed more than 250 machines while remaining based in Los Angeles.

Risks & controversies

The business is shaped by cannabis regulatory constraints that bar interstate commerce and require state-by-state production facilities. Competitive pressures include lower-cost integrated pre-roll lines, production-as-a-service pricing models that eliminate customer capex, and the potential entry of large tobacco equipment manufacturers whose scale could commoditize the processes Sorting Robotics automates at premium price points.
